AUGUSTA-RICHMOND COUNTY ADMINISTRATOR'S OFFICE To: The Honorable Larry Sconyer~, Mayor Honorable J.B. Powell and Members of the Engineering Services Committee Charles "Randy" Oliver, County Administrator Patrick S. Dillard~~ S:-:V~ Engineering Services Manager From: Date: February 10, 1997 (February 3, 1997) fnstallation of Telemetry System for Richmond County Water System Project No. U-96-007 Re: Caption: Approve change order NO.1 in the amount of $29,132.00 for Engineer Service Corporation regarding the installation and set-up of Telemetry System for Richmond County Water System. Background: Engineer Service Corporation (ESC) was awarded the installation and set-,up of the Telemetry System under a lump sum Contract. The Telemetry (SCADA) System is utilized to monitor and control the Richmmld County water system operation. The SCADA system controls all pumps, wells, tank elevations 1 etc. At the time of bidding it was unclear whether existing tank level transducers could be utilized with the new system. Therefore, ESC included an optional pay item in their proposal of 5625 per site if new transducers were fOl~nd to be necessary. New transducers were required at; 12 'tank sites. Also, this Department requested from ESC ap inventory of certain spare parts to keep on hand in order to make expedient minor r'epairs to the system. The maj or . costs involved in this change order is due to the need to temporary remove and reinstall the base radio and antennas from the Georgetown elevated water tank. This tank is scheduled for painting this April and must have all antennas and attachments removed. Analysis: Approval of this change order wo~ld authorize complete payment for services perfo!.'med and estabJ.ish funds required to remove and reinstall base statlons as described herein. Prior to removal of the existing base radio and antennas from the Georgetown Tank, an identical new base station should be installed and brought into operation on the Lumpkin Road elevated tank. This would eliminate any down time in OUl.- control of the water system. Once the painting of Georgetown Tank is complete the original base . ft..,., ..... T Page 2 station removed from this tank would be reinstalled. In addition to the elimination of down-time for our system, this would also provide this Department with a secondary base station left on the Lumpkin Road Tank. Financial Impact: The Funding required for this change order is $29,132.00. A breakdown of the cost are shown on the attached prepared Change Order and corresponding attachments. Alternatives: An alternative regarding the removal of the base radio station would be to remove all the radio and antenna equipment from the Georgetown Tank and re-install it permanently on the Lumpkin Road Tank. This would cause a complete down-time of the whole Telemetry System for an estimated time of between 24-36 hours providing no problems or damage to equipment is encountered. Recommendation: Recommend approval of Change Order No. 1 for Engineer Service Corporation in the amount of $29,132.00. The alternative and consequential down-time presented above is not recommended by this Department or the installers (ESe) of the Telemetry System.

This procedure would eliminate any "down time~ on the SCADA System providing total system continuity and would provide you with some additional spare radios and antennas. The other alternative would be to remove all of the equipment from Georgetown and re-install it on the Lumpkin Tank. The down-time would be 24-36 hours providing we had no delays or damaged any equipment in the move. The cost to provide either of these options is as follows: I.
